I'd say that the Animator Bar needs a couple more improvements to be considered finished, though it's taken some steps forward recently (drag & drop, fixed importing, etc).
I like the idea of a visual representation of the angles when an animation is clicked; that could probably be squeezed in somewhere. A preview is also important, though it couldn't be fitted into the bar, so an alternative solution would have to be engineered.
Anyway, I like the ideas and agree that it needs some polish and further work, so hopefully future builds reflect this.
